So the killer feature I really love about WebspirationPRO is its "RapidFire" mode (activated by clicking on a lightning symbol), so that it's very easy for a user to rapidly add new nodes to a map via simple keyboard maneuvers. It'd be really great too if the final feature (if implemented in CmapTools) could further allow 100% keyboard manipulation to permit the traversal and accession of different nodes with pure keyboard action (the idea being to eliminate any and all required use of the mouse).

I would love to see pure keyboard support, as well. Some of the web- and desktop-based mind-mapping programs do this very nicely and are so quick to use. If anyone wants to test usability for basic tree creation, you can have a look at the keyboard control of 'mindmup', for example. Basic tree structure creation is pretty fast (and fun). Of course, no ability to do the things that really matter for concept mapping.
